IMO, we have never encounter anything but facts. If you state that you say "materialist reality", because it could have been a "spiritual reality" (to put an example) then are you really saying that reality is "made of matter"? Simply logic, don't claim it is philosophy.
Actually, "facts" are not things we encounter. "Facts" are abstractions.
Note that I refer to a "'materialist' reality" in order to accommodate your language. That's not anything I would say or claim, myself.
But when I say that all we encounter is the material world, so to speak, this does not imply that it could actually have been a spiritual one. That's like saying if we see horses, they could have been unicorns. The spiritual stuff was just dreamed up by people, but it has been debunked.
And yes, clearly the universe is made up of non-spiritual stuff -- that is, what we can call (in layman's terms) material stuff... matter and energy... spacetime. And no, that's not philosophy. It's all this other junk creeping into your posts that's philosophy.
Once you strip that away, you're left with something very mundane... this plain old world of stars and gas clouds and whatever the "dark" stuff turns out to be, and so forth. But nothing spiritual... unless you use the term "spiritual" so loosely that it means something like "consciousness" even tho consciousness is the activity of the physical brain.
You rail against the materialists, but whenever we get down to brass tacks, turns out the materialists are right.
